1  Game Development / Newbie & Debugging Questions / Beginner question: appropriate container for vertices and normal coordinates ? on: 2012-08-15 11:29:27
Hallo everybody,

I am storing coordinates of a 3d model within 3 ArrayLists. One List for the vertices, 1 for the normals and one for the faces. It is working as long as there are not too many vertices in one 3d model. Trying to load a model consisting out of 12000 vertices for example causes trouble because I get an error indexoutofboundException or even a unknownsource exception when trying to get one element out of one list by using the get() method (for ArrayLists).
Isn't an ArrayList self-managing in "how much space is needed" for the 3d model ?

Or is the another "Container, Array, otherList,..." which is much better to store these coordinates when there are a lot of it?

Thanks, with kind regards
Alexander
2  Game Development / Newbie & Debugging Questions / Beginner question: Using vbos with vertexHandle/normalHandle causes trouble on: 2012-08-15 11:19:35
I am loading a 3d model within java by parsing an *.obj file which was created by exporting it out of Blender. So far so good the import is working.
I am storing all vertices and normals coordinates in an 2 ArrayLists<Vector3f>. Thats working.

I am getting into trouble when importing 2 or 3 different models, because glgenBuffers() is returning values 1 and 2 when creating vbo_vertexHandle and vbo_normalHandle for the first object, 3 and 4 for the 2nd object and 5 and 6 for the 3rd object. Do I hav to have ONE global vertexHandle (all vertices of all 3 models) and ONE global normalHandle (all normal indices of all 3 objects) -> so I only have to work with Handles 1 and 2, or may I as I supposed store the vertexHandle and normalHandle for each object within the 3dmodel instance (1 and 2 for obj01, 2 and 3 for obj02...) and using them dependingly on WHICH model I want to render?

Do anyone perhaps know a good src to learn how to deal with 2 or more different 3dobjects ( in java I mean real instances not only drawing  2 quads Wink )?

Thank you for the possible answer.
regards Alexander
3  Game Development / Newbie & Debugging Questions / How can I bundle a jar?including /res folder into thefinal jar using any bundler on: 2012-08-05 15:27:15
I want to export my eclipse opengl project and this is working so far. But using jarsplice to bundle all libraries, natives and the main method to one final *.jar doesn't work: the /res folder (including *.png's and a 3dmodel cant be included into that *.jar.

Does anyone know a solution that esults in ONE *.jar with included data?

Thanks very much...
4  Game Development / Newbie & Debugging Questions / Simple OpenGl application is not working outside Eclipse using "jarsplice" on: 2012-08-04 18:48:39
Hi,

I am working around a simple 3d Render Application, which does import an *.obj file for constructing the 3d-model...

All runs fine using Eclipse when pressing the run-Button...
So I wanted to bundle all together with the above mentioned software "jarsplice". I added all jars and natives, so far so good BUT  and I dont really know what to enter/type in when to chose the package+main-class... (Perhaps anyone knows the beginner projects of "codimg universe") or can have a short look over the project structure and say me which is the right name for the main class..
If anyone can help me with that It will probable take not longer than 5 or 10 minutes over Skype... search for the nick "abe_no_i"...

I was trying a lot but can't bundle it anyways...
